Key generation algorithmLattice basis reductionPartial key exposure attackIn 2003, L. H. Encinas, J. M. Masqué and A. Q. Dios proposed an algorithm for generating the RSA modulus N with a large private key d ,
Abstract The implement tenique of RSA public-key algorithm and RSA signature algorithm has been presented. RSA cryptosystem is a public-key cryptosystem .The key components of the implement are keys generation ,encryption and decryption. Therefore, the big number structure and its operations, then g...
Generating the public and private key pair is the most complex part of RSA cryptography. Two large prime numbers, p and q, are generated using the Rabin-Miller primality test algorithm. A modulus, n, is calculated by multiplying p and q. This number is used by both the public and private...

The proposed algorithm makes use of four large prime numbers which increases the complexity of the system as compared to traditional RSA algorithm which is based on only two large prime numbers. In the proposed Enhanced and Secured RSA Key Generation Scheme (ESRKGS), the public compone...

The RSA algorithm involves four steps: key generation, key distribution, encryption and decryption. A basic principle behind RSA is the observation that it is practical to find three very large positive integers e, d and n such that with modular exponentiation for ...

RSA is fundamental to modern cryptography and is used in a variety of security protocols and applications. Its strength lies in the computational difficulty of factoring large composite numbers. References RSA Wiki Cryptography: RSA Algorithm open SSL...
This article first introduces the basic principles of the RSA algorithm, including the generation, encryption, and decryption processes of public and private keys. Next, it elaborates on how to apply the RSA algorithm to website encryption, including user identity authentication, data encryption ...
